Patented sept. 4, 190e.

Beit known that I, WILLIAM L. DOLIER, a citizen of the United States,residing at Phila` delphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Im rovements inDriving Mechanism for Centnfugals, of which the following is a secication.

Itis the o ject of my invention to provide an electric-motor drive for acentrifugal machine, the motor and centrifugal basket being adapted togyrate together about a common omt of support; and it is particularlythe object of my invention to gain a saving in vertical height or headroom in the combined motor and centrifugal apparatus. To

close up Ato the hanger as possible, and the bracket for supporting themotor-field element extends upwardly beyond the hanger and is securedupon an inner spindle.

invention resides, further, in features hereinafter pointed out andclaimed.

Reference is to be had to the accompanying drawings, in which- Figure 1is a general view in elevation of the e ectric motor as applied to acentrifugal Fig. 2 is a vertical view, artly in section and partly inelevation, of tlie hanging device and the electric'motor. Fig. 3 is aside view of the bracket carrying the lower bearing ofthe motor. Fig. 4is a plan view of the motor, showing the spindle and hollow shaft insection.

its bottom has a At 1 is represented any fixed body, such as a girder ortankffrcm which is hung the combined centrifugal and driving-motor. A bse member 2 is bolted to the under side of the ember 1, and to the base2 is secured the hanger 3. This hanger 3 is hollow and at perforationforallowing the passage of the non-rotatable spindle 4 therethrough.This perforation is slightly larger in diameter' than the spindle 4 atthis point to plermit gyratory movement of the spindle wit outengagementiwith the hanger 3. In thei'lower en of the hanger 3 is aspherical cavitgl lined with a surfaced mass of metal a, 'ch bears thespherical member 5. This member 5 has cut in it a vertical slot b, whichembraces an extension c on the interior of the memberf. Member 5 issecured to spindle 4 andin consequence of the extension c said spindleis inca able of rotation. Because of considerable E ay between the slotb and the extension c t e spindle 4 and the member 5 A hanger 3. i Toadjust member 6, it may be compressed to a greater portion ofthe shaft14 is the armature-spider may, however, deflect or gyrate in anydirection. Upon spindle 4 is mounted the motor and centrifugal, and itis about the member 5, therefore, that any deflectionof the centrifugaland motor takes place. As resilient means for opposing the deflection ofthe spindle 4 there is supplied a mass of rubber or like material 6,embracing the indle 4 and filling the upper end of the the resiliency ofthe or less extent between the washers 7 and 8. The lower washer 8 bearsagainst a flange 9 on the spindle 4, and the upper washer 7 is held inany position desired by means of the washer 10 and set-screw 11.

The spindle 4 extends downwardly through the motor and Lust. beyond thecentrifugal basket 1.2, whic revolves within the housing 13. i

14 is a-hollow shaft surrounding the spindle 4 and secured to thecentrifugal basket 12 2,.

to drive th`e same. Mounted upon the upper 15, carrying the armature 16.It is t erefore by the armature 16 that the shaft 14 and the centrifugalbasket 12 are driven.

The member 17 is secured at its lower extremity byscrew-threads to theshaft 14, and within the member 17 'is maintained a quan- .tity oflubricating-oil, which passes down between the spindle 4 and the linnersurface of the shaft 14 and is drawn off at the bottom of thecentrifugal. This oil may be introduced through the opening 18, whichembraces the hanger 3. The surface 19 of the member l17 is employed formechanical braking, a brake-strap 20 being drawn against the surface y19by the lever 21, controlled by the handle 22.

As seen in Fig. 2, the arrangement of the brake-Wheel and lubricator issuch that the armature of the motor is brought as close as may be to thehanger 3, thus economizing space and reducing the dimensions of theentire apparatus.

. The motor herein shown is of the mltipolar type, whose field-ring oryoke is shown at 23 and whose poles are shown at' 24. Upon each pole isa shunt-winding 25 and a series winding 26. The field-ring 23 is securedin the bracket 27, extending upwardly and be ond the hanger 3. y Theupper extension of the spindle 4 enters #the center of bracket.27 and iskeyed to said bracket to prevent any relative motion. '27 is a cen- IOOIVO

tering-screw by means of which the field is properly -adjusted withrespect to the armature. From this structure itis apparent that thefield-ring 23 is supported by bracket 27 and by means of said bracket 27maintained always in the same relative position with re-4 um of thebracket 27 carries the field of themotoralso, so that there may be norelative l l motion between the armature and the field.

from the field-ring of the motor an In other words, the motor swings asan entirety withl the centrifugal about the member 5. As a furthersteadying means for thefield portion of the motor I employ the bracket28, which is secured at its upper end to the field-ring 23 andcarries atits lower end the bearing 29, through which passes-the shaft 14. Thisbracket is not indispensable.

The brushes 30 of the motor are sup orted bear y'upon the commutator 31in the well-known manner;

From the foregoing description it is ap arent that I.v have devised anelectrical rive for centrifugals in which the greatest econv om in spaceor head room has been effected an in which the field and armature of themotor occupy at all times the same relative position with res ect toeach other irrespective of the centri gal or its deflection.

A hand-lever 64 is mounted upon the curb 13 and is adapted tocommunicate with'the electric controller forthe motor.
